These are two different things. Youtube ads can potentially found in all videos and you don't really have a choice because there's no practical alternative to Youtube. So you either pay or use an adblocker (while it works). There's value in Youtube and I can easily see why would someone pay for the ad-free subscription. Then again creators who choose to advertise or promote commercial products in their videos have a fraction of the leverage that Youtube has. If you don't like them, simply don't watch those channels and find something else. By choosing to promote products they'll implicitly choose to filter out some segments of their potential audience, and that's their choice. Youtube has nothing to do with that, they would place promotions in their videos no matter what service they use as their video outlet.
